Triumph is one of the most iconic and revered names in the history of motorcycling. Established in Coventry in 1885, by the start of the 1900s the company had made its first motorcycle, beginning a continuous run of production under various ownership until its eventual closure in 1983. After many years of inactivity, the brand was brought back to life in the 1990s by businessman John Bloor and has gone on to re-establish itself as one of the most desirable names in motorcycling. In 2008 to mark the Bonneville’s golden anniversary, Triumph worked with Hollywood actor Ewan McGregor and motorcycle fashion manufacturer Belstaff to produce two specially designed Bonnevilles. The clothing firm produced a bespoke design incorporating a sophisticated Black and Gold colour scheme synonymous with the fashion brand’s identity. Watsonian is one of the longest lasting names in the British motorcycle industry, founded in 1912 the company continues to manufacture hand-built sidecars in the Heart of England. The GP 700 sidecar has a modern suspension and glass fibre body, but with a spoked wheel and alloy nose strips to evoke the style of the era when British motorcycles dominated the world.

This unique sidecar outfit brings together 3 iconic British brands in one package. The Belstaff Bonneville was made in very limited numbers with many going on display in Belstaff’s flagship stores around the world. Bought new by the vendor in 2008 the bike was taken to Watsonian to be attached to a GP700 sidecar which was then colour matched by Altamura Concepts of Surrey, the design house that painted the original bikes for Triumph. The GP700 is Watsonians wide-bodied version of the popular Grand Prix, with a generous bench seat capable of carrying an adult and a small child or two children. With its classically styled octagonal nose, aluminium beading and stainless-steel front chassis sections it has a tremendous presence on the road and will always attract an admiring crowd, especially when combined with such a rare bike. The Bonneville is in standard trim apart from a flatter profile front tyre and a steering damper and the sidecar still has its original unused tonneau cover and rain cover. A very striking combination that would cost over £20,000 to put together today, it comes supplied with all of the original owners’ manuals, a full set of keys and a current V5C with a matching number plate TR58 BEL (Triumph 1958 Belstaff).
